4:77Have you not considered those who were told, “Restrain your hands, and perform your prayers, and spend in regular charity”? But when fighting was ordained for them, a faction of them feared the people as God is ought to be feared, or even more. And they said, “Our Lord, why did You ordain fighting for us? If only You would postpone it for us for a short while.” Say, “The enjoyments of this life are brief, but the Hereafter is better for the righteous, and you will not be wronged one bit.”

4:90Except those who join people with whom you have a treaty, or those who come to you reluctant to fight you or fight their own people. Had God willed, He would have given them power over you, and they would have fought you. If they withdraw from you, and do not fight you, and offer you peace, then God assigns no excuse for you against them.
